The complete Sesamers guide to European semiconductors: where the money went, who is building and funding it, the three questions the sector cannot agree on, and how to get in.
Any company designing or manufacturing chips, photonic components, or the specialised hardware used to make them – chip design, photonics and optical computing, quantum computing hardware, and semiconductor manufacturing equipment. We include the physical component layer for AI infrastructure (optical switches, specialised chips) and exclude companies that only consume chips to build a downstream product.

The desks
Each one is a live page – this pillar is the way in
Global supply chain disruption exposed Europe's dependency on Asian and US chip manufacturing, triggering the EU Chips Act and a wave of sovereignty-driven funding.
2023-24
Design over fabrication
Given the capital intensity of building fabs, most European venture funding concentrated in chip design, photonics and specialised components rather than competing on manufacturing scale.
2025-26
AI infrastructure bottlenecks drive the largest rounds
Companies solving physical bottlenecks in AI data centre infrastructure – optical switching, specialised interconnect – are now raising the largest rounds in the vertical, exemplified by iPronics.
Three open questions
Where informed people in this sector genuinely disagree
Can Europe build a globally competitive chip manufacturing base, or is design-only the realistic ceiling?
The EU Chips Act commits significant public capital to semiconductor manufacturing, but leading-edge fabrication remains concentrated in Taiwan, South Korea and the US.
The case forEuropean manufacturers already lead in specific niches – lithography equipment, automotive and industrial chips – and targeted public investment can extend that leadership into new specialised categories without needing to match leading-edge logic fabs.
The case againstBuilding a competitive leading-edge fab requires tens of billions of dollars and specialised talent concentrated almost entirely outside Europe; public subsidy alone has not closed that gap in other regions that tried.
Where we land: Design and specialised manufacturing niches are realistic; leading-edge logic fabrication at scale is not, within this decade. European policy that accepts this and doubles down on existing strengths (lithography, automotive chips) is more credible than policy chasing parity with TSMC.
Is photonics genuinely a distinct category, or does it get absorbed into general semiconductor investing as the technology matures?
Several funds and companies on this desk treat photonics as its own specialised category with dedicated expertise.
The case forPhotonic computing and optical interconnect require genuinely different physics and manufacturing processes from electronic semiconductors, justifying specialist investors and a distinct talent pool.
The case againstAs photonic components become a standard part of data centre and chip architecture, the specialist framing may fade the same way other once-niche hardware categories eventually got absorbed into mainstream semiconductor investing.
Where we land: The specialist framing holds for now because the manufacturing processes and applications remain genuinely distinct, but expect gradual convergence as photonic components become a standard line item in broader semiconductor and AI infrastructure deals.
Does EU sovereignty-driven capital risk funding weaker companies over better global alternatives?
A growing share of European semiconductor funding carries an explicit strategic-autonomy rationale alongside financial return expectations.
The case forChip supply chain dependency is a genuine strategic vulnerability exposed by real shortages, and some public capital accepting lower financial returns for supply security is a reasonable trade-off, not a market distortion.
The case againstDirecting capital toward European semiconductor companies primarily for sovereignty reasons, rather than because they are the best global option, risks propping up sub-scale players that cannot compete once the subsidy ends.
Where we land: The sovereignty rationale is legitimate for genuinely strategic categories (defence-relevant chips, critical infrastructure) and weaker as a blanket justification across the whole vertical. The funds doing this well are explicit about which bet is which.
How to get in
Three audiences, three short lists
If you are building
Decide early whether you are design, manufacturing equipment, or a physical component – each has an entirely different capital intensity and timeline.
Get ESA, EU Chips Act, or an industrial partner's validation early – it is the closest thing to independent technical due diligence this sector has.
Name a design partner or customer before you raise growth capital; the largest rounds this year had one.
Pick investor-facing events over broad trade shows; this vertical's buyer base is narrow and technical.
If you are investing
Ask for the contract book, not just the pipeline – semiconductor sales cycles are long and design wins take years to convert to revenue.
Underwrite capital intensity honestly; manufacturing-heavy companies need multiple large rounds to reach revenue, not one.
Check whether sovereignty-driven capital is co-investing for strategic or purely financial reasons, and whether that changes the company's incentives.
Use the funding desk to see who actually led rounds in the last 24 months.
If you are buying or partnering
Ask for flight heritage or an equivalent validation milestone before committing to a hardware supplier.
Understand the full supply chain dependency of any component you are sourcing from a European semiconductor startup.
Check lead times and manufacturing capacity honestly – this sector's supply constraints are real.
Use the startup desk for a shortlist; verify claims directly given the technical complexity.
Who to know
Start on the desks – profiles update as we verify them
A chip company that designs semiconductors but outsources actual manufacturing to a specialised foundry, rather than owning its own fab.
EU Chips Act
European Union legislation aiming to double the EU's share of global chip production and strengthen semiconductor supply-chain resilience.
Optical interconnect
Using light rather than electrical signals to transmit data between chips or servers, reducing latency and power consumption in data centres.
Design win
When a chip design is selected by a customer for use in their product, a key milestone in semiconductor company revenue even before mass production begins.
Leading-edge fabrication
Manufacturing chips at the smallest, most advanced transistor sizes, currently concentrated in a small number of Taiwanese and South Korean foundries.
Why does this vertical have no dedicated events desk yet?
No European trade show has yet been verified with confirmed semiconductor-specific programming to the bar this site requires. Sourcing one is a priority.
Is this the same as industrial automation and IoT?
They overlap – several photonics and sensor component makers are tagged to both – but semiconductors covers the chip and component layer specifically, while industrial automation covers the systems built on top of it.
How often does this page change?
The numbers come from the desks and move weekly. The written analysis is reviewed quarterly and the review date at the top is the honest one – if it is stale, the analysis is stale.
Can I suggest a company or fund for the desks?
Yes. Use the suggest links on each desk. We verify before publishing; paid placement does not get you onto a ranking or directory.
Counts are generated from the desks and refresh weekly. The written analysis is editorial and reviewed quarterly. Corrections and additions: contact the desk
